Specification of Letters Patent.

- Patented May 18, 1915.

Application filed January 5, 1914, Serial No; 310,487. Renewed April 16,1915. Serial No. 21,847.

To all whom. it may concern:

Be it known that I, PIERRE J. Pannier, a citizen of the United States ofAmerica, residing at Salem, in the county of Harrison and State of WestVirginia, have invented certain new and useful Improvements inGlass-Blowing Apparatus, of which the fol-- lowing is a. specification.

This invention relates to certain new and useful improvements in glassblowing apparatus and more especially to such class of devices in whicha blowing and a suction is mechanically eii'ected.

An object of the invention is to provide an air blowing and an airsuction member operatively connected with the blow pipe for operatingupon the glass cylinder which is being manufactured, for instance in theprocess of making sheet glass.

A further object is the provision of an elevating device for the blowpipe with its glass cylinder so arranged that the blow pipe isautomatically disengaged from the air tube at a predetermined point inits Vertical line of travel.

Another object is to provide in connection with an air tube having anoperating suction and blowing fan, a graduating valve for the tubeadapted for automatically opening and closing upon imparting verticalmovement to the blow pipe and said tube.

A further object is to provide an air damper in the air tube of theblowing system govcrnable for eXhausting desired quantities oi airtherefrom.

A still further object is the connection of a separate suction andblowing fan with the pipes of the air tube system and whereby said fansmay be governed atwillin con nection with the air tube and the blow pipewhile the piping ot the system is advantageoiiisly hinged for allowing avertical movement ol the blow pipe relativeto the main stationarypiping.

Another object is the provision of a vertically movable hoist havingstationary vertical guides and furnished with means for disengagealilysupporting the blow pipe and air tube, each in relatively movablepositions.

A still further object is to provide a swinging horse adapted forreceiving the glass cylinder when vertically positioned upon the hoistand operable for moving the cylinder to a horizontal position suitablycushioned by means carried by the horse.

With these objects in view and others that will appear as the nature ofthe invention is better understood, the same consists in the novelcombination and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings and pointed out in the appendedclaims.

In the drawings forming a part of this application and in which likereference numerals, designate corresponding parts throughout the severalviews :Figure 1 is a side elevation of the apparatus illustrating thebait of the blowing pipe as collecting its quantity of glass from withinthe collecting ring of the glass pot, the ring and pot being shown insection. Fig. 2 is a sectional detail View of the regulating valve inthe air pipe or the system. Fig. 3 is a view similar to Fig.1 butillustrating the glass cylinder as completed and with the blow pipeseparated from the air tube, the air tube, blow pipe and cylinder beingshown in their elevated positions. Fig. 4 is a sectional detail view ofthe air damper found in. theair tube. Fig. 5 is an enlarged detail viewof the tripping hoist mechanism supporting the air tube and blow pipe,the air system pipe and glass cylinder being broken away. Fig. (l is adetail. view of the regulating valve shown in Fig. 2 looking into thepiping and one of the connections being shown in dotted lines. Fig. 7 isa side elevation of the swinging horse about to engage the verticallysus' pended glass cylinder, and Fig. 8 is a similar view showing thecylinder resting horizontally upon the horse.

In the operation of mechanically blowing glass into cylinders for themanufacture of sheet glass it is desirable to provide a carricr for theblow pipe and bait, whereby the latter may receive the desired quantityof glass from a point within the collecting ring and may then beelevated during the blowing operation and until. the completion thereofwhile a suction device is serviceable for then exhausting the air fromthe cyliu der. It is now devised therefore to provide a blow pipe 10having an upper and a lower annular ring 11 and 12 respectively, whilethe pipe at the bottom thereof terminates in the usual bait 13. The airtube 14: is adapted to lit over the upper end of the blow pipe 10 andrest upon the upper side of the ring 11, while this tube is connected bythe regulating val vc 15 illustrated in Figs. 2 and 6 to the hingedpiping 16 and 17 of the stationary air piping 18 of the system.

Forsupplying air under pressure to the piping system for use by the blowpipe 10,

having the operating rod 26. A damper 27 within the connecting pipegoverns the flow. of air from the fan 19 to the system, while a similarvalve 28 in thetransverse pipe 23 controls the suction action of theM1121 upon the air'piping system. I

A hoist block 29 is provided'upon one or both of its opposite sides withrings or eyes 30 slidably engaging the guide rods 31 secured to theceiling and passing there- 'through, A hoisting cable 32 passes over thepulley 33 also secured to the ceiling and is connected to the upper endof the hoist block as at 34, it being noted that the weight of the blocknormally retains the same in its [lowered position, while the cable isutilized as an elevating means.

- Three hooks or. open semicircular brackets are secured in alinement tothe inner face of the block 29 and adapted to receive the blow pipe.therein with the ring 11 supported by resting upon the upper face ofthe hook-35. lith the air tube 14 resting nponathe. ring 11, a furtherhook '36 upon the block 29'za1icl'siinilar to said'hooks 35 is adaptedto receive and assist in positioning said air tube while a pivoted hook37 of silnilfaitdiorni and provided with a rear extensionor handle 38 ispivoted to the top of said block as at 39, While said hook is normallypositioned and swung beneath the annular ring 40 of the tube 14 asillustrated in Fig. 1.

With the apparatus positioned as shown in Fig. l, thebait has received aquantity of glZtSS".l:1"fFOIrlf2L point within the annular collectingring '42 *positioned upon the molten glass 43 of the" pot 44. With thehooks positioning the blow pipe 10 and the pipe ring 11 resting upon theupper hook, an upward movement'of the hoist block being imparted by thecable 32 elevates not only the blow pipe 10 and its bulk of glass 41,but

- also the air tube 14 resting upon said ring 11, so that the valve 27may be opened to allow the fan 19 to blow directly through the pipingsystem to the blow pipe and its glass, during the'drawing operation inFig. 5.

and thereby forming the glass into a cylinder 45 simultaneously with itsupward movement.

. When desired to exhaust the air from the glass cylinder 45, the blowervalve 27'- may be closed and the suction valve 28 opened, whereby, withthe damper 25 opened, the suction fan 21 will accelerate and thereupon aclosing of the damper 25 will forcibly exhaust the air from the pipingsystem and the glass cylinder 45.

.The graduating valve 15 consists of the connecting pipe sections 46 and47, each having a portion of its diameter closed by a block 48 and soarranged that the com- ,municating' passage is substantially half:

open when the pipe hinge and the piping are positioned lowermost asshown in Fig. 1, but will be opened at its widest extent when the pipehinge is positioned at its upper limit of travel as shown in Figs. 3 and6. The molten glass being gathered as shown in F 1 with the blow pipeand bait in its lowermost position,th e hoisting mechanism is elevatedas rapidly as desired, while the blowing andsuction fans 19 and 21 aresuitably regulated for their desired effect upon the glass. Atsubstantially the limit of'the upward travel of the hoist block, theregulating valve 15 will be automatically fully opened by means of thepipe hinge blocks as hereinbefore described, while the arm 38 of thehook 37 will engage the stationary hook 49 secured to some stationarymember 50, so that the continued upward movement of the hoist blocktilts the hook 37 upwardly upon its pivot 39 whereby said hook engages ibeneath the 'collar 40 of the tube 14, automatically'unseating said tubefrom the supporting ring 11 and entirely disengaging said tube from theblow pipe as best shown Within theair tube 14 a plate or cylincloselyfit therein and .provided with a projecting pin 52 protruding throughthe angular slot 53 of the tube and whereby the sleeve drical sleeve 51is positioned adapted to slot 53 upon the proper manipulation of the pin52 as will be at once evident from an in spection of Fig. 5 of thedrawings.

The complete operation of the device will be apparent from the abovedetail description from the time of attaching the bulk of glass totheblow pipe bait until the blow pipe with its completedcylinder isautomatical-1y disconnected-from the air tube. The action of theblowing'as well as the suction fan for operating upon the glassthroughthe air piping is also clear and the manual regulation of bothblowing and suction air as well as the automatic reguluating valve 15.

Whenever desired also, the sleeve valve 53 move the same from the hoistby means of the horse consisting of the frame 60 hinged at 61 to thefloor 62. A longitudinal slot 63 at the upper end of the frame isengaged by the sliding roller 64 rigidly secured to the endless belt 65,which belt passes over the drum 66 and the pulley 67 thus giving aswinging movement to the frame upon a movement of the belt by means ofthe motor 68 in either direction and controlled as desired. At the-upperend of the frame an extending arm 69 braced by the rod 70 terminates ina hook 71 of semicircular form and adapted to engage beneath the ring 12of the blow pipe 10 and to thereby support the same and upon a downwardmovement of the frame to elevate the blow pipe ofi the book 35 of theblock 29 upon which it has been resting. Spring mounted semicircularbrackets 72 are spaced apart fromthe frame 60 and adapted to receive theglass cylinder cushioned thereon, while the frame 60 is provided with aspring-pressed foot 73 upon its lower side and adapted to rest upon thefloor when the frame and cylinder are positioned horizontally as shownin Fig. 8.

The operation of the take down device will be clear from thisdescription, it being designed to remove the completed glass cylinderfrom its support and to change its position from the vertical to thehorizontal reclining position without any liability of injury to thecylinder. It is apparent that the cylinder may then be transferred fromthe horse or may be treated thereon or annealed in the usual manner.

While the forms of the invention herein shown and described are what arebelieved to be preferable embodiments thereof, it is nevertheless to beunderstood that minor changes may be made in the form, proportion anddetails of construction without departing from the spirit and scope ofthe invention set forth in the appended claims.
